You want to hide wiring? Is it in conduit or armored cable? Exposed wiring is illegal in the US...sounds like you are in another country? So if getting the wires behind the wall can't happen, putting it in extruded metal tubing (EMT or conduit) is a safer option. Then embrace the necessity and go for a hi-tech/industrial look. Reclaimed and re-imagined furnishings and parts from factories and workshops to play up the look. Search "industrial" under the "browse rooms" tab in the Houzz header. Regarding hiding switches...hiding them is not so great...you kind of want them accessible when stumbling about in the dark! The EMT electrical system has metal boxes for mounting switches, outlets and light fixtures. And metal cover plates too.

Hello Ankit, you need to send complete details and requirements for positive results. There is only one W/C on each floor, no washing area in the kitchen etc. For a proper and planned house , you need to take care for the basic requirements first. My suggestion is that you must take professional help for a perfect planning.
